I think part of what scares them is that they didn't see us coming. They were hanging out with us, enjoying our company, thinking that we are pretty cool - and one of
them.
Finding out that their neat little definitions of us are completely wrong and that we are the dreaded "other", throws them into a narrow-minded spin.
With such people, I know longer even try to explain to them what my type is, only that it is not
them. If someone is already so ignorant, they are not going to get my fondness for gender-benders. Because the next thing out of their mouths is going to be something about what I really want is a
real man but I don't know it because I am fucked up in some way. AT THIS POINT - someone is about to be slapped.
Of course, different situations call for different levels of disclosure. And maybe we can educate a few people in situations like these. But sometimes, it's just useless.
